EYEGLASSES.

Specification of Letters latentd Patented Mar. 5, 1912.

Application filed September 1 8, 1907. Serial No. 393,432.

To all whom it may concern;

Be it known that I, LEO F. ADT, of the city of Albany, county of Albany, and State of New York, have invented certain new and useful Improvements in Eyeglasses;

and I do hereby declare the following to he a full, clear, and exactdescription-of the same, reference being had to the accompanymg drawings, forming a part of the specification, and to the reference-numerals marked thereon.

This invention relates to eyeglasses of the type in which the nose guards are mounted:

to swing on a suitable support toward the nose under the action of springs, and it has for an object to provide a construction in which the springs act as thesole means 101 retaining the guards on their support so that the connection and the disconnection of the parts may be facilitated.

A further object of the invention is to provide a spring that is sightly and at the same time efficient and durable and one that may be connected to the parts upon which it operates in a simple and convenient manner. Y 7

To these and other ends the invention consists in certain improvements'and com- I binations of parts all as will be hereinafter more fully described, the novel featuresbeing pointed out in the claims 'at the end of the specification.

In the drawing: Figure 1 represents a front view of apair of eyeglasses constructed in accordance with this invention, the. lenses being. partly broken away. Fig. 2

represents a top view of one of the guards and adjacent parts of the eyeglasses. Fig. 3 represents a bottom view of one of the guards and adjacent parts, and Fig. :4 is a section on line as-a of Fig. 1. ;Fig. 5 is a detached detail perspective view.

. Eyeglasses. constructed in accordance with this invention comprise a support which preferably consists of a 'subst-antiallyrigid low bridge land lens attaching devices 2 arranged at the ends of the bridge and'secured to lenses A. Swingingly mounted on the support are guardsfeach of which in the. present embodimentconsists of a lever having a nose bearing portion 3 at its rear end and. a finger piece at itsfront end, the lever preferably being made from flat stock and mounted on the upper face of the support and-the finer piece being formed by twisting the 'stoc at 4 and bending itjfiat wise and outwardly at 5 in front of the nroximate lens attaching device 9- so that W-lll not be conspicuous.

The swmglng connectlon between, each guard and the support comprises coiiperating bearing members which detachably con- I nectthese parts, and in this instance consist of a laterally opening bearing formed by the walls of a recess 6 .provided in the lever of the guard, and a rigid pivot 7 mounted on the support beyond the'b'iidging-portionand having a head 8 or other overhanging portion which prevents the vertical movement of the guard. -These bearing members are retained in cooperatlve relation to retain a guard on the support by means of a spring which also serves to position theguard. This spring preferably is in the form of a fiat-spiral com arranged on that side of the support opposite the guard, in the present instance on the underside. At one end, in this instance theinnerend, it ha s detachable connection with the support asby a transverse opening in a stud 9 arranged on theunder side of the support in vertical. alinement with the axis of the nose guard, while at the other end, 1n this instance the outer, it is detachably connected to. the guard as, for example, through the medium of an upwardly projecting hooked end 10 which overhangs the rearwardly projecting portion ,of the guard. In the present instance the hook is formed by bending the l'llltellal of the spring upwardly and 'inwar 1y, edgewise, and I also find it preferable to bend the rearwardly extending arm or portion of the guard lever slightly downward, as shown,

'75 prised of a ribbon of'fiat material and is 1 at the point at which it cooperates with ger pieces, or operating arms, tocOin'press the springs, and then releasing t-h em, For the purpose of removingthefsprmgs or the guards it is only necessaryato disengage the hooked ends '10 6f the from guards and Withdraw their other ends from the openings in studs 9. The guards maybe removed as soon as releasedfrom the springs. o 1

Eyeglasses constructed in accordance with this invention are inexpensive to manufacture, as they consist of aininimnm number of kparts, are less liable to getout of order, an when broken,

- Further, it isapparent that"thehnou'nting of the springs is adapted for use with eye .glasses in which the nose guards are not 1 spring in the direct-ion necessary retained Ion the support by the springs I claim as my invention:

"In an eyeglass mounting, the combination with a support, a nose guard, and cooperating bear ng members pivot-ally conuecting the' guard and the-support, of a spring for positioning the guard'mounted independently of the bearing members and held in detachable engagement with the. guard and vwith the support by action of the to turn the guardon-its pivot.

3. In aneyeglass mounting, the combination with ahsup'port, of a guard mounted to tu-rn on one, side of the support, and a coil spring arranged on the other side of the support vand heldin detachable engagement with thesupport and the guard bythe action of the spring in the direction necessary to turn the guard.

4. In an eyeglass m'ounting, the combination with a support having-an overhanging portion thereon, of a swingingly mounted nose guard arranged beneath .and in engagernent with said overhanging portion and movable laterally from under the same,

In an eyeglass mounting, the combination with a support and a nosev guard, one

of the parts having a fixed pivot and the other having a laterally opening bearing receiving sald pivot, of a spring supported the pivot, acting ina diwith; the pivot and having its ends held in detachablein erlocking. Qnne tiQnfwith the ,g iardgandth pp t v v c, Spr ng; 9;;
